Because the ESRP priority of A is now lower than that of B, A becomes the slave, and B
becomes the master.
Configuring the PxM for Multiple VLANs
When the PxM has multiple VLANs, if you intend to set up redundancy using ESRP,
you must make all of the VLANs domain members of a master VLAN, using the
following ExtremeWare command:
config vlan <master vlan tag> add domain-member <other vlan tag>
You can then configure ESRP for the master VLAN as if it were the only VLAN. See
"Using ESRP with the PxM" on page 8-6.
The following example ExtremeWare script sets up several VLANs as domain members
of a master VLAN, and configures ESRP for two redundant BlackDiamond systems
(SW1 and SW2) containing PxM modules.
# create VLANs, designating one as the master
create vlan v1
create vlan v2
create vlan v3
create vlan master
# configure VLAN tags
config v1 tag 280
config v2 tag 281
config v3 tag 282
config master tag 100
# configure VLAN IP addresses
config v1 ipa 10.65.28.2/26
config v1 ipa 10.65.28.3/26
config v2 ipa 10.65.28.65/26
config v3 ipa 10.65.28.129/26
# configure VLAN ports
config v1 add port 7
config v2 add port 1,8 tag
config v3 add port 1,8 tag
config master add port 8 tag
